6412 2023-09-18 Lab none Loaned Loaned none Loaned to Gracie Pearsall at UCSC for a informational display at Elkhorn Reserve
4000 2019-06-13 Lab none Tested Lab none Tested but we probably can't use this sensor any more. We put in new AA lithium batteries, and the miniDOT was able to power up, but the LED light continuously blinks 2x, "card error." We tried re-formatting the card, using another 2GB card previously used in a miniDOT (could have been a bad card), and then with a good SD card at EE. In all cases, the LED status light still indicated a "card error."
3999 2019-05-23 Mayberry DO Sensor E Removed Lab none Brought back to the lab for testing. The o-ring was warped and it was damp inside. There was some corrosion on the board and the batteries were dead.
3997 2018-11-28 Mayberry DO Sensor E Maintenance Mayberry DO Sensor E Swapped 2x AA lithium batteries
3965 2018-10-04 Mayberry DO Sensor E Notes Mayberry DO Sensor E Measured at -45 cm.
4529 2018-02-28 Mayberry DO Sensor E Moved Mayberry DO Sensor E We're guessing this is when the sensor was moved from -62 to -45cm.
3964 2017-10-13 Lab none Installed Mayberry DO Sensor E After the barnacle was removed in the lab, reinstalled at MB on the floating boom, lower position.
3963 2017-08-16 Mayberry DO Sensor E Removed Lab none Removed from lower position (-62 cm) on floating boom and brought in to the lab for barnacle removal.
3959 2017-05-25 Mayberry DO Sensor D Moved Mayberry DO Sensor E Moved from static boom (upper position, -10 cm based on water level on 2017-05-10) to floating boom (lower position, -62 cm).
3955 2017-05-10 Mayberry DO Sensor E Mayberry DO Sensor D sn 1220 moved from middle position (-38 cm based on water level on 2017-02-23) to upper position (-10cm based on water level on 2017-05-10) with the other 2 miniDOTs.
2634 2017-02-23 Mayberry DO Sensor F Moved Mayberry DO Sensor E Moved from the bottom position on the fence post in the channel to the middle position on the new water sensor boom.
2498 2016-10-11 Mayberry DO Sensor D Moved Mayberry DO Sensor F Due to the lowering of the water to flush the salt, this sensor was no longer in the water, but could not be removed because it was rusted to the chain. It was moved to the bottom/lower location by inverting the chain.
1604 2014-10-16 Lab none Installed Mayberry DO Sensor D Installed at 26cm below the water surface on the fence post in the channel.
1601 2014-10-09 West Pond DO Sensor A Removed Lab none Removed from West Pond for installation at Mayberry where a longer profile is possible.
1588 2014-09-25 Lab none Installed West Pond DO Sensor A Installed at West Pond in a profile at 13cm above soil in water column.
1569 2014-09-24 Lab none Maintenance Lab none Using the miniDOTControl program I set the time and set the sample interval to one minute.
